(CNN) — Bill Nye’s viral YouTube video pleading with parents not to teach their children to deny evolution has spawned an online life of its own, with prominent creationists hitting back against the popular TV host.

“Time is Nye for a Rebuttal,” Ken Ham the CEO of Answers in Genesis writes on his website. Answers in Genesis is the Christian ministry behind the Creation Museum in Petersburg, Kentucky.

Nye’s criticism of creationism went viral earlier this week, after being posted last Thursday.

“I say to the grownups, if you want to deny evolution and live in your world, that’s completely inconsistent with the world we observe, that’s fine. But don’t make your kids do it,” Nye says in his Big Think video, which has been viewed nearly 3 million times.
